What a great practice! My daughter just got her braces off and the results couldn’t be better. Don’t get me wrong – her teeth look phenomenal – but what is super amazing is what y’all have done for her self-esteem. She wouldn’t even smile the day we walked in for our initial consult because she was so self-conscious of her crooked teeth, which is a terrible thing to watch a teenager deal with. Now her teeth are beautiful and she knows it, so I finally get to see my little girl smile brightly once again. Thank you all, from the super friendly ladies up front who welcome us in each time to everyone who makes the magic happen in the back!!!! – Facebook Review

If you need an orthodontist go to Dr. Greenberg!!! I have 6 children and my last 3 have been with Dr Greenberg! I wish I had know about him for the older 3. He is very good! Personable and has a GREAT staff!!! I never have a hard time getting in and have never felt put out if something needed to be fixed. I have recommended him to others and have all had a great experience as well! – Kim B.

My friend referred me to Dr. Greenberg’s office and I found it very easy to make an appointment once I called. They had a couple available options early before work or near lunch which worked well with my schedule. During my past two visits, I barely had to wait as they attended to me right on time. Their staff is very nice and helpful, as I had a couple of questions to ask and I felt like they were giving me honest answers. It’s a stress-free doctor’s office that gets you in and out in a timely manner. – Kirby C

My son and I love Dr. Greenberg! He is an honest orthodontist that truly wants to help children have beautiful teeth. Dr. Greenberg is so knowledgeable and I believe the best in this area. – Jennifer S.
